Having now fully describedniy said in venticin, what l claim and desire to secure hy Letters Patent is l. ln a carburetor, the combination of a casing formed witli'air inlet openings, a spraying nozzle veiftieaily and centrally disposed in the casing, a valve for controlling the openings in the casing, a spring inten posed between the valve and the nozzle, n'ieans for admitting a supply of liquid fuel and air to the nozzle, means for operating ihe valve to close the .penings and prevent operation. of; the nozzle,l including si'i'eu" threads latween the easing and the valve, and a handle extending from theA valve.

L. ln" a earlnnetei, the combination of a casing formed With ait` inlet openings, a vertical seat and an opening in the bottom ol' the latter, a vertically movable element having a flanged portion which operates in the easing, and a centrally disposed stem which operates in the seat, the stem having 'a reduced portion at its cui to nornialljv close the liottonij opening, said stem having a duet which extends through i'r'oni near the bottoni to the top of the element, the duet being flared at its upper end, the stein having inclined aill inlet openings which coin- By these I municate with the flared portion of the ductand a space formed between the element and the casing, the. easing having an air inlet port for the passage of air to Said space, a valve for controlling the admission of air to the casing, and resilient meansfor holding the eleinent down to normally close the bottom opening in the bottom of the seat.

il. In a carburetor, the combination of a easing, a vertical extension in the bottom of the easing formed in its bottom with a fuei inlet opening. a circular conical shell having 'a central vertical stem reduced at its lower end to normally close the fuel inlet opening, said stem having an opening extentlin from the hottoin to the, top of the stem anshell, the uppei` end of the opening flaring outwardly. the stein having inclined openings helowlhe top of the shell and communicating with the lared portionof the opening, the outlets of the inclined openings being dibposedout of alinement with each other to whirl the fluid passing through the opening to the "using, the casing having an o ening for the admission ofair to the incline openings in the stem, and a spring acting on the shell for normally closlng the fuel inlet opening.

In testimony whereof have hereunto set my hand inr presence of two witnesses.
